Abstract
A multi-layered implant has at least two layers, of which at least two have a different porosity. A woven or knitted mesh, e.g., can be provided completely or partly with a porous fleece layer on one side or on both sides. The porosity can vary within a fleece layer. A layer of the multi-layered implant can also consist of a film. Resorbable and non-resorbable substances are considered as materials.
Claims2

- a woven mesh having a top side and a bottom side;
- and
- a porous fleece layer mounted to the top side of the mesh wherein said fleece has a porosity in the range of about 100 to about 1,000 liters/(m.sup.2 s) gas low measured at an inlet pressure of 200 PA, a test surface of 50 cm.sup.2 and a test thickness of 1 mm,
- wherein the woven mesh and porous fleece layer are made of a resorbable polymer selected from the group consisting of Polyglactin 910, Polydioxanone, Poliglecaprone 25 and combinations thereof.
